Is that true in Canada's geology? I work on a number of coal seam gas projects here, specifically on the water management side. Water management is THE issue with CSG (CBM for you guys). Two big problems: 1. Huge volume of water. 2. It's too saline to be useful water. Hell, it's too saline to discharge, it'll kill everything in it's path. So we build some big-ass ponds.
Another potential issue that the hydrogeologists are working on is whether removing that much water from the coal seams will depressurize adjacent aquifers of better water quality, which are being used for water supply.

And it gets better when you add some hydrogen to the natural gas. It burns even cleaner and more efficiently. Disclaimer: holds ASX:EDE.
